The term “cyborg,” as a combination of “cybernetics” and “organism,” was coined by Manfred Clynes and Nathan Kline in 1960 in a paper presented at a National Aeronautics and Space Administration (NASA) conference on space exploration as a representation of a particular challenge of space travel: physically adapting a human body to survive in a hostile environment rather than modifying the environment. Soon after, NASA commissioned “The Cyborg Study” to investigate the theoretical possibilities of incorporating life support–related technologies into future spacecraft design. From the beginning, cyborgs were seen as the realization of a transhumanist goal—liberating humans from the limitations of the body and its environment by means of mechanization. Outside of space exploration, the term “cyborg” has evolved to encompass an expansive mesh of the mythological, metaphorical, and technical. Initially mainly taken up by science fiction writers to create superhumans, the notion entered cultural studies in the 1980s, particularly through Donna Haraway’s feminist “cyborg manifesto,” which argues that we are all cyborgs. Since then, terminology has shifted, and cyborgs are more likely called “posthumans,” “more-than-humans,” “other-than-humans,” or “companion species.” Discussions of cyborg and posthuman subjectivities in educational research have taken two main directions. The first argues that with equipment like tablets, smartphones, and laptops, students and teachers are already cyborgs—hybrids of human and machine—accessing information, resources, networks, groups, personal relations, libraries, and mass media through the Internet. Other research has investigated how the construction of cyborg and posthuman subjectivities changes the relationships between humans and their surroundings, devising new social, ethical, and discursive ways of thinking and representation.
